DETACHABLE BUTTON.

SPECIFICATION forming part of Letters Patent N o. 666,855, dated Janlfary 29, 1901. Application filed July 16, 1900. `erial liloL 23,760.(N0 model.)

To @ZZ wtont it TV1/ty concern:

Beit known that I, WILLIAM U. RAINE, a citi/.en of the United States,residing at Milwaukee, county of Milwaukee, and State of Wisconsin,haveinvented new and usefullmprovements in Detachable Buttons, of whichthe following is a specification.

My invention relates to improvements in detachable buttons.

The object of my invention is to provide more reliable holding devicesthan those heretofore used and to adapt such devices for use oncloth-covered buttons, regard being also had for neatness of appearanceand simplicity of construction.

In the following description reference is had to the accompanyingdrawings, forming part of this specification, in which- Figure l is acentral sectional view of my improved button, drawn ou a line crossingthe springretaining channel. Fig. isasimilar view taken at right anglesto that of Fig. l. Fig. 3 is a View of the shank and baseplate. Fig. lis a top view with the cap removed.

Like parts are identified by the same reference-letters throughout theseveral views.

The head of the button is composed of the cap A and -a holding-plate B,the latter being provided with a channel C and stem-tube D. The cap A isadapted to fit over the holdingplate B, as shown in Figs. l and 2, andwhere the cap is covered with cloth E the edges of the latter areinserted between the parts A and B, and thereby securely held in place.The edge of the capA is turned in at a after the holding-plate B isadjusted in position, thus preventing the removal of the latter.

A flat spring is doubled upon itself to form the spring-arms F andarranged on edge in the channel C, as best shownin Figs. l and 4. Thisspring is preferably formed with a central bulge in its respective armsto facilitate the entrance of the shank. The edges b of theholding-plate B are preferably turned downwardly, Fig. 4, to cover theends of the spring and hold the latter in the channel.

Referring to Fig. 3, it will be observed that the base G is formed witha shank H, having its sides tapered at g near its upper end and its endprovided with a head I, having barbs J. The sides of the head I are alsotapered,

as shown in Fig. 2, thus giving it a wedge shape, which facilitates itsinsertion between the arms F of the spring.

When it is desired to unite the parts of the button, the shank H isinserted through the stem or shank tube D, with the barbs in a planeparallel with the sides of the spring-arms F. Owing to the wedge-shapedcontour of the shank-head I the spring-arms-are easily separated lopermit the passage of the shank, which is given a quarter-turn as soonas the barbs J have cleared the spring-arms. The latter are thenpermitted to spring inwardly against the tapered sides g of the shank,when a slight backward movement of the latter causes the barbs to engageover the sides of the spring-arms, as shown in Fig. l.

When it is desired to release the button, the base and shank are pressedinwardly and turned a quarter-turn, thus separating the springs andbringing the barbs into a position for withdrawal. The base ispreferably provided with a notch M, indicating the position forwithdrawal.

I am aware that it is not new to provide buttons with holding-springsand headed Shanks; but I believe I am the lirst to provide a shank witha barbed head in combination with holding-springs adapted to be engagedthereby.

What I claim as new, and desire to secure by Letters Patent, is-

1. A detachable button, comprising a holding-plate, provided with achannel therein and a central tubular aperture; a cap covering saidholding-plate and channel; springarms located in said channel; and abase provided with a shank having backwardly-projecting barbs, adaptedto enter said tubular aperture and permit the engagement of said barbswith said spring.

2. A detachable button comprising a holding-plate; a cap covering thesame; a cloth covering for the cap-plate, having its edges engagedbetween the holding-plate and the cover-plate; a base provided with ashank adapted to enter the holding-plate, and havingbackwardly-projecting barbs; and flat spring-arms supported on edge bythe holding-plate, and adapted to be engaged by the barbs of said shank.

3. A detachable button, comprising a hold- IOO ing-plate; aeap therefor;inberposed springholding-plate; and a base provided with a arms; and abase provided with a shank havshank havingl backwardly-projeoting barbsing baokwardly-p'rojecting barbs adapted to adapted lto enter lbhechannel between the engage the arms, said shank beingt-aperedspring-arms, and to engage the same. 5 below the barbs, and saidspring-arms being In testimony whereof I aix my signature x5 arranged topress elastically against the tain bhe presence of two witnesses. peredsides of the shank.
